What are the indications for referring a patient with warts to a specialist?

Indications for referring a patient with warts to a specialist are not explicitly detailed in the provided UK guideline excerpts. However, general clinical practice and dermatological referral principles suggest referral may be considered if warts are extensive, refractory to standard treatment, causing significant symptoms or functional impairment, or if there is diagnostic uncertainty or suspicion of malignancy.

Since the provided context does not include specific guidance on wart referral, it is advisable to refer patients with warts to a specialist if:

• Warts are persistent despite appropriate first-line treatments.
• There is diagnostic uncertainty about the lesion.
• Warts are causing significant pain, bleeding, or functional problems.
• There is suspicion of an atypical lesion or malignancy.

For precise referral criteria, consultation of dedicated dermatology or skin infection guidelines is recommended.
